Still tweaking my Nova list

Having issues getting in to peoples back fields for grabbing objectives, etc so I added an Elysian detachment. Also started playing around with the bombard. I like to think of it as my dark reaper killer (or anyone who thinks they're safe with a 2+ cover save - but especially dark reapers...hate dark reapers).
